' 1 Claim. (mar-26) This invention relates to plows and is particularly related to two-way plows.

The primary object of the invention is to pivotally mount two oppositely disposed plow bottoms to the plow beam, means being provided for holding the plow bottom assembly to a predetermined angle to the beam. To carry out this object the standard of the plow bottom assembly is pivotally mounted to the beam and is identical in shape on each side of the pivot point, having a plow bottom secured to the standard on each side of the pivot in the usual manner.

Another object of the invention is to provide a stop associated with the beam for holding the plow bottom assembly and its standard at a predetermined angle to the beam, means provided for adjusting this angle relative to the beam.

A further object of the invention is to mount the handles of the plow rigidly relative to the standard and the plow bottoms so that when the plow is reversed the handles will be at the proper angle to the beam.

Another object of my invention is to provide specially constructed hand holds that will remain relatively cool when exposed to the heat from the sun in warm weather.

A still further object of my invention is to provide a special clevice on the forward end of the beam for changing the width of the furrow.

These and other incidental objects will be apparent in the drawings, specification and claim.

Referring to the drawing:

Figure 1 is a side elevation of my new and improved two-way plow as viewed from the land side.

Figure 2 is an enlarged detail fragmentary view of the beam of the plow, showing the standard pivotally mounted thereto, parts :broken away for convenience of illustration.

Figure 3 is a fragmentary sectional detail taken on line 3-3 of Figure 1, showing the stop mechanism for holding the plow bottom to a predetermined angle relative to the beam.

Figure 4 is an enlarged detail fragmentary view of one of my new and improved self-cooling handles, parts broken away for convenience of illustration.

Figure 5 is a sectional view, taken on line 55 of Figure 4 looking in the direction indicated.

Figure 6 is a plan view of my new and. improved two-way plow.

Figure '7 is a fragmentary side view as viewed from the mold board side of the plow, the dotted line position showing the relative movement of the plow bottom assembly relative to thebeam of the plow. V .In the drawings:

My new and improved two-way plow'consists of a beam I, having the standard 2 pivotally mounted at 3 to the beam. There are two plow bot-I toms mounted to the standard, one right and one left. I These bottoms are of well known construction, consisting of the mold board 4, share 5, land side 6 and the frog 1, which is bolted to thestandard 2 by the usual bolts8. Each side of the standard 2 disposed opposite of the pivot point 3 is identical to its opposite side, and each' of the plow bottoms are identical except for one being right and one being left.

In order to hold the beam and the standard relatively snug or tight at the pivot point, a cross bolt 9 having a spacer l0 clamps the bifurcated end I l of the beam against the side of the standard. As wear takes place between the bifurcated end of the beam and the standard the spacer It] may be refaced allowing the bifurcated ends H to come closer together when the bolt 9 is cinched up taking up the wear that has been developed.

A pair of handles l2 and I3, preferably of tubing are also secured to the pivot bolt l4 and have suitable bracing l5 for maintaining their relative position between the respective plow bottom assemblies and the standard 2. Hand holds l6 are fixed to the outer ends of the handles l2 and [3, as best illustrated in Figure 4, wherein a stub I1 is inserted within the handle, said stub being part of the hand hold [6 and secured therein by any suitable means.

The hand hold consists of a cross section as illustrated in Figure 5, wherein parallelly disposed semi-circular cross section bands l8 and H! are spaced apart by the web 20, having openings 2| for permitting air to circulate through and around the structure, the structure of the hand hold being all cast in one unit. By the use of this particular structure I find that the heat of the sun never heats the handle, which is of great assistance to the carrying out of the entire spirit of my invention. Referring to the clevis 22 located on the forward end of the beam, it will be noted that this clevis is reversible as illustrated by the broken lines and is only designed to regulate the width of the furrow.

I will now describe the operation of my new and improved two-way plow. When the depth of the furrow has been determined, the adjustable stops 23 are positioned relative to their distances from the beam l by the use of the adjusting holes 24 located on the depth control member 25 which 3 is bolted to the beam at 26. It will be noted from the above description of the clevis and the depth gauging member 25 that each has its purpose, the olevis to control the width of the furrow and the depth member 25 controls the depth of the furrow.

It will be noted that the handles l2 and I3 are also shown in full lines in this particular setting, but when it is desired to make the turn on the end of the furrow, the plow bottoms are reversed to the position shown by the dotted lines, wherein the tip 30 of the plow bottom 2! will engage the stop 23 and the plow is turned half over at this 1 time ready for the return furrow.

I wish to bring out that the primary object of my invention is the pivotal mounting of the plow bottoms and their standard to the beam of the plow and providing a depth member that, has:

adjustable stops for engaging each of the plow bottoms, controlling the angle of the plow bottom' A two-way plow comprising a beam, a standard pivotally mounted intermediate its ends on the beam, oppositely disposed plow bottoms on the standard, each carried adjacent an end of the standard and having a tip, a depth control member fixed to the beam and extending beyond opposite sides of the beam, stop means adjustably mounted on the depth control member on opposite sides of the. beam, the tip of the idle plow bottom engaging the stop on its side of the beam to determine the depth of operation of the operative plow bottom.
